Abstract

PROBLEM TO BE SOLVED: To facilitate the protection and deletion of the arbitrary number of messages and the management of the received message by collectively deleting the plural messages which a user selects among the plural stored messages or designating the protection of the messages. SOLUTION: The execution of the deletion and protection of the message is selected. In the case of deletion, MD=1 is set and MD=0 is set in the case of protection. A control part retrieves the storage area of a message storage slot and displays all the slot numbers of the message slots where '1' is set in a use situation on a display part 8. The user selects the slot number of the message to be deleted or protected by switches 9 and 10. When the slot number of the message to be deleted or protected is inputted, the control part of a receiver inverts/displays the selected slot number. The control part judges deletion or protection from the value of MD. In the case of MD=1, the message which is not in a protection state is deleted among the selected slot numbers.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio selective call receiver and a message management method thereof, and more particularly to a radio selective call receiver provided with means for simultaneously deleting a plurality of messages selected by a user or designating protection. And how to delete or protect that message.

[0002]

2. Description of the Related Art A radio selective call receiver (hereinafter abbreviated as a receiver) amplifies and demodulates a radio signal received from an antenna from a base station (not shown) by a radio unit, and decodes the signal by a control unit. The control unit compares the decoded signal with its own call number written in the individual number storage unit, and when they match, fetches data, notifies an incoming call, and stores the transmitted message to the storage and display unit. Is displayed. The user operates the switch to manage the protection and deletion of the received message.

FIGS. 6 to 10 show a conventional example of message management in this radio selective call receiver. The received message has a fixed number of characters as shown in FIG.
Sectors (S1, S2,..., S)
m), and one message is a message file (F1, F2,
.., Fn).

FIGS. 8 and 9 show sectors and message files.
As shown in (1), the use status is managed as a status determination area, and "1" is set when the sector or message file is in use status, and "0" is set when it is not used.

A message is stored in n message storage slots (M1, M2,..., Mn) as shown in FIG. 10, and together with a message file, a message number added by the transmitting station, a reception time, an emergency call The designation and the like are stored. Here, the number added to M, 1,
2,..., N are the numbers of the messages allocated by the receiver and are called slot numbers.

[0006] Each time the number of received messages increases, the slot Mi
Is moved to Mi + 1 (i = 1 to n-1), and management is performed so that the latest message is always stored in M1. This management is the same even after the message storage slot is full, and the oldest Mn message is automatically deleted. At this time, if the message of Mn is a protection designation, the message is stored without deletion, and the presence or absence of the protection of the immediately preceding slot Mn-1 is confirmed. Is moved to Mi + 1. Next, when the number of received messages increases, Mn-1
If the message is a protection designation, the message is not deleted in the same manner as described above, but the presence or absence of the protection of the slot of Mn-2 or less is confirmed, and the transfer is performed. Once all messages have been designated as protected, no further messages can be received.

[0007] The flow of processing relating to message deletion and protection will be described with reference to FIG. The deletion and protection of the message are displayed in a menu format by operating the switch after reading the message (step S201). When the user selects the message of the slot Mk (k = 1 to n) to be read and deleted, the content of Mi + 1 is moved to Mi for the slot number equal to or more than (K + 1). However, when k = n, only deletion is performed (step S2).
02, S203).

When the user selects protection, "1" is set in the protection item of the message storage slot (steps S204, S205).

[0009] The conventional receiver further has a function of deleting all messages, and can delete all the messages including the message in the protected state collectively (steps S206 and S20).
7).

[0010]

In the above-described conventional radio selective call receiver, only two types of message deletion can be performed, individually or entirely. Also, protection can only be done individually. Therefore, since the user needs to set protection and deletion for each message, it takes time to protect and delete an arbitrary plurality of messages that are not all in number.

[0011]

SUMMARY OF THE INVENTION According to the present invention, there is provided a radio selective call receiver for storing and displaying a received message, wherein a plurality of arbitrary messages selected by a user among a plurality of stored messages are provided. Means for deleting or specifying protection at once.

The received message is stored in a storage circuit (RAM or EEPROM) in the control unit 3. The configuration of the sector storage area, the message storage area, the sector status determination area, and the message status determination area is the same as the conventional one (FIG. 6). To FIG. 9). The feature of the present invention is that the configuration of the message storage slot (unit storage area) is different from the conventional one.

FIG. 2 shows a configuration example of the message storage slot of the present invention. The configuration of the present example shown in FIG. 2 is compared with the conventional configuration shown in FIG.
Has been added. In FIG. 2, if "1" is set in the item of use status, the slot is in use, and if "0" is set, the slot is unused. Other items of protection, a designated file, a message number, a reception time, and an emergency call designation are the same as those in the related art.

Next, the message management operation of the receiver according to the present invention will be described with reference to the flowchart shown in FIG. 3 together with FIG. 1 and FIG.

When the user performs a predetermined operation on the switches 9 to 11, the control section 3 enters a message slot management menu and displays predetermined information on the display section 8. The user operates the switches 9 to 11 while looking at the display information on the display unit 8, and inputs the next instruction (step S101).

First, the user selects whether to delete or protect the message (step S102). MD = 1 is set for deletion, and MD = 0 for protection. M
D is a flag for knowing whether to delete or protect (steps S103, S104).

The control section 3 searches the storage area of the message storage slot shown in FIG. 2, and displays all the slot numbers of the message slots for which the use status is set to "1" on the display section 8 (step S105). .

The user selects the slot number of the message to be deleted or protected by using the switch 9 (applying a mark: instructing the menu to move down) or the switch 10 (applying the mark: instructing the menu to move up).

When the slot number of the message to be deleted or protected is input, the controller 3 of the receiver highlights the selected slot number (step S).
107).

The above steps S106 and S1
The process of 07 is continued until a selection end instruction is input. The end of the selection is input in the same manner as the selection of the slot number (step S108).

Subsequently, the control unit 3 checks the value of the MD and determines whether the MD is a deletion or a protection (step S109).

When MD = 1, a message that is not protected is deleted from the selected slot numbers. Deletion in this process is to set “0” in the item indicating the usage status of the message storage slot in FIG. 2 (step S110).

Next, processing is performed so that messages remaining after deletion are stored without missing numbers from the smaller slot number. First, assuming that i = n and j = 0 (step S111), the usage status of the slot Mi is checked. j
Is a counter for counting the number of consecutive slots whose use state is "1" (step S1).
12).

If the usage status of Mi is "1", j = j
+1 (step S113), the value of i is confirmed (step S114), and if i = 1, i = i-1 (step S115), and the process returns to step S112 to use the next slot Mi-1. Check the situation.

In the process of step S112, M
If the use status of i is "0", the value of j is confirmed (step S116). If j = 0, there is no data to be moved, so the process proceeds to step S114 to proceed to step S114. Make a confirmation.

In the process of step S116, J = 0
If not, the contents of Mi from (i + 1) to (i + j) are moved to Mi-1 (step S117).

By repeating the processing of steps S112 to S117, the message is stored without missing numbers from Mi.

In the processing of step S109, M
In the case of D = 0, the protection is inverted to "1" if the protection designation of the selected slot number is "0" and to "0" if it is "1" (step S118).

FIG. 4 shows a display example of the display section 8 when a message is deleted. In the example of FIG. 4, the display screen has a display area for five lines.
As shown in (B) and (C), display is performed over a plurality of pages. The current mode is displayed on the top line of each page. In each of the second and subsequent lines, the protection designation, slot number, reception time, and one sector of the message are displayed from the left end. The * mark in the protection designation column indicates that the corresponding message (slot number: 2, 4, 5, 6) is designated for protection. In the actual screen, the slot numbers 3, 7, and 8 surrounded by dotted lines in the figure are displayed in reverse light and dark, and a message corresponding to the highlighted slot number is deleted or protected. Indicates that it is selected.

[0036]

As described above, according to the present invention, when a message is protected or deleted, the identification number (slot number) of the unit storage area storing the message is displayed in a list, so that the user can arbitrarily select a plurality of messages. Since the user can select individual messages and simultaneously protect or delete the messages of the selected slot number, the user can
